Colombia’s business community may be shielded from a war crimes tribunal, but that doesn’t stop judges from investigating if businessmen made a fortune off murder and displacement.

A court in northern Colombia issued an arrest warrant against mining executive Edgardo Percy and the investigation of 15 others for their alleged involvement in the killing, disappearing and displacing of farmers, according to Verdad Abierta.

Percy is former manager of the La Jagua mine, which was operated by the company Carbones de Caribe.

Together with other members of the regional elite, the La Jagua chief allegedly masterminded the killing and displacing of poor locals by paramilitary group AUC between 1997 and 2006 in order to buy their land for a fraction of the price.

Carbones de Caribe, through their parent company Cementos Argos, sold the La Jagua property to Prodeco, a subsidiary of Swiss giant Glencore in 2005.
